Initially, I was hesitant to upgrade from my Canon EF 100 - 400mm IS I to the ISII. After all, I had taken some great photos with the original lens. My primary use of this lens is wildlife photography, for which this lens offers a practical alternative for those who cannot afford the 'big guns'.

Given its substantial cost, it took me a long time to decide to buy this lens. I'm so glad I did. It has lived up to and surpassed all my expectations. The lens is super sharp of course, but it's the image stabilisation and focus speed that make it a joy to use.

This lens is just awesome..super happy, image quality is mind blowing.

This is a great lens. When I borrowed on my son told me, "These are the best freakin pictures you have ever taken." The next day I purchased one from Digital Goja through Amazon. The questions I had were answered quickly. All the products arrived as promised.

This is my second 100-400 lens. I absolutely love the new version even more than the previous one I bought about about 15 years ago. This is my go-to lens for sports photography. I can use it sitting in the stands and I always get great shots.

None

Newest of the new design of the 100-400 from Canon. Twist focus and new 3 level stability.

Flawless Finish; New Design Tripod Mount; twist zoom; Unparelled Clearity

Weight

Lens was well worth the wait. Pictures are sharp and clear. Full frame and vary, vary fast focus. Works well with Canon's 1.4 converter.

This is an excellent lens and a wonderful alternative to the very expensive primes in this focal length. Focus drifts a little but it may be my camera settings are not optimal for the lens

Can't beat the L quality lens I am using this lens with 7D giving me effect range of 160-640, the 3 modes of IS and very good close focusing (almost like macro lens) has made lens my favorite. The quality of pictures especially sharpness is simply superb!

This eagerly awaited telephoto zoom lens replaces the old 100-400mm lens in Canon's lineup of professional lenses. Its predecessor was popular due to its relative compact size, light weight and good value for money.

Good sharpness; Excellent build quality; Novel zoom ring resistance adjustment; Relatively lightweight; Reasonably low distortion; Weather and dust resistant; Low CA; Image stabilisation; Fast autofocus

More expensive than the old 100-400mm ever was; but differences may be worth it to some
